Temperature experiment: heat-reflective blanket wall lining

[Igloo Ed]

I had based my 1 inch hole size on warmth and carbonmonoxide levels with my stove and lantern setup but I will need to consider the oxygen needed for a more efficient flame.
I burn my canister stove on a very low setting and the flame seems to burn just fine. The lantern does seem to be a little weak though and I will see if a larger hole makes a difference in both the stove and the lantern.
I suppose it also makes a difference on how many people are in the igloo concerning the vent size needed. I usually don't have any more than three in an igloo and most times it is two or solo.
Thanks again Matti, for sharing your knowledge.

I do love being corrected when I can learn from it!

This is a good guideline for hole sizing. I will aim for a 1 or 1.5 inch hole for most purposes then, and larger for more people or cooking. Alternatively if I build in inside liner again, I might consider a sliding door for the vent.

By chance I was back out to the igloo this weekend (5 hour drive from here) and measured the vent...3.5 inches..! So, it could have been 3 inches with the insulation method I used. Clearly, I have to run my experiment again some time in the future!

If you're not having fun, you're not doing it right!
